Abstract

A new epimerization mechanism was introduced for the polymerization of propylene obtained by octahedral benzamidinate complexes. Deuterium labeling showed that deuterium is transferred from a methyne to a methylene position in the polymer inducing a stereoerror and an elastic material. In addition, two active species are formed during the polymerization of propylene promoted by the octahedral bis(benzamidinate) titanium dialkyl complexes. [Figure not available: see fulltext.]
